Group Work in Schools

While this post pertains to business schools, it's just as true regarding high school:

Group work is largely an academic joke, a process where the weaker members of the group rely almost exclusively on the stronger, more conscientious students to carry them all to the grade they want. (Of course, the same “weak rely on the strong” dynamic prevails in real-world group work as well.) Group work serves lazy students and professors quite well — the low-performing students can relax while their peers complete the task, and the professors have fewer papers or projects to grade.

I remember very few group projects in high school, and only a couple of group projects in college (where I remember everyone pulling his/her own weight).
